【摘要】 Lucool涤纶/氨纶针织物是一种新型吸湿排汗弹性面料,将弹性性能和吸湿快干性能良好的结合在一起,本文对六种不同参数的Lucool涤纶/氨纶针织物进行综合研究。首先,将Lucool涤纶长丝与氨纶以全添纱方式编织成六种不同参数的纬平针织物,并测试织物的力学性能,研究氨纶含量、线圈长度等对织物力学性能的影响。其次,研究了氨纶添纱针织物的尺寸性能,探讨线圈长度与织物密度、平方米克重的关系以及线圈形态系数和紧密系数的关系。通过测试织物的热湿舒适性能,研究了氨纶含量、线圈长度等对织物热湿舒适性能的影响,同时探讨了织物在受拉伸时,线圈形状、大小的变化对织物性能的影响,以及不同拉伸率对织物透气性和透湿性能的影响关系。最后,通过研究织物的延弹性性能,建立四元件模型,并验证四元件模型与织物蠕变过程的拟合程度,研究了氨纶含量、加压时间、反复拉伸次数和加压大小等因素对织物拉伸变形率的影响,测试Lucool涤纶/氨纶针织物的弹性疲劳性能,发现织物的弹性抗疲劳性能优异。更多还原

【Abstract】 Lucool/spadex plated plain knitted fabrics is a new type of fabrics, which has excellent properties of moisture transferable, fast drying and elasticity. This paper integrated studied six kinds of Lucool/spadex plated plain knitted fabrics which have different parameter. First of all, Lucool/spadex plated plain knitted fabrics were knitted in circle knitting machines, and mechanical properties of fabrics were tested, the results show that the mechanical properties are affected by spandex content and stitch length. Secondly, the dimensional property of fabrics was studied, and some dimensional parameters of knitted fabrics were tested. Regression analysis found that the fabric density and fabric weight linearly decreased with increasing of stitch length. Also, the relationship between loop pattern coefficient and tightness coefficient was researched. Furthermore, thermal and moisture comfortable performance of fabrics were tested, Analysis found that performance of thermal and moisture is affected by spandex content and stitch length. Fabric properties changed with drawing of fabrics. By means of regression analysis found that the relationship between wet permeability and draw ratio is linearly related. Finally, fabric elastic properties were researched, and mathematic model was established, and the fitting degree of the model and creep process of fabric which is higher was tested and verified. By analysis found that the elastic properties are affected by spandex content, drawing time, and repeatedly drawing number, tension size, and so on. Also the fatigue property of fabric was tested, and the result shows that the fatigue property of Lucool/spadex plated plain knitted fabrics is excellent.更多还原
